tolerance stack up software
are there any free or not "tolerance stack up" tools available on the web?
this would apply to mechanical engineering.
check out our whitepaper library.
not free, try
i have never ran across a stackup program that i was happy with.  honestly, i find that mathcad or excel are the best at what i need to do.  you just have to make sure you set everything up correctly.
i normally use excel when i need to.
we looked at a product called sigmundedge 18 mths or so ago.  it was the version of their software that works with solid edge, i believe they have other options for other cad packages.  they also had a more complex version that takes statistics & probablities into account.  it had some interesting capabilities, i would have like to trial it, but i'm not convinced it was a silver bullet.
the two i have run across are both ug embedded. tolmate and vsa. both now owned by ugs or i guess now since seimens purchased it owned by seimens. in my humble opinion i believe tolmate does a better job of analysis.

there are three main tolerance analysis packages that are worth your time. vis-vsa, cetol, and 3dcs.
i have used both vis-vsa and cetol for many years.
sigmetix, the company behind cetol, has me teaching their basic cetol classes. i been doing 3d tolerance analysis for 17 years, with 8 years at vsa.
